Please consider replacing agutils.status_bar with tqdm

[lrvdijk]

I am trying to create updated bioconda packages for rnaseqc (see (1) and (2)).

I was also trying to create a separate bioconda recipe for the python utils, as published on PyPI (see (2) above). That package, however, depends on agutil, a package not available on either bioconda or conda-forge.

Since rnaseqc only uses agutil for a progress bar, would it be an idea to instead use the much more widely used library tqdm for that?

I could open a PR if desired.

Thanks!
